Question

这个问题一直被问到，但我找不到答案。我有一个使用spring boot的应用程序，intellij可以毫无问题地运行它，但java -jar echohostname.jar给我这个错误：

Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean

这是我的主要课程：

public class ApplicationMain {

    public static void main(String[] args) {


        SpringApplicationBuilder builder = new SpringApplicationBuilder(SpringConfiguration.class);
        ConfigurableApplicationContext applicationContext = builder.run(args);


    }

这是我的Controller类：

@RestController
public class Controller {

    @Autowired
    @Qualifier("getSigarProxy")
    private SigarProxy sigarProxy;

    @RequestMapping(value = "/hostname", method = RequestMethod.GET)
    public String hostName() throws SigarException {
        return "HELLO THERE";
        //return sigarProxy.getNetInfo().getHostName();
    }
}

这是spring配置类：

@SpringBootApplication
@Configuration
@ComponentScan("controller")
public class SpringConfiguration {

    @Bean
    public static PropertySourcesPlaceholderConfigurer getPropertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean
    public Sigar getSigar() {
        return new Sigar();
    }

    @Bean
    public SigarProxy getSigarProxy() {
        return SigarProxyCache.newInstance(getSigar(), 1000);
    }

    @Bean
    @Scope("prototype")
    public HttpHeaders getHttpHeaders() {
        return new HttpHeaders();
    }

    @Bean
    @Scope("prototype")
    public AsyncRestTemplate getRestTemplate() {
        return new AsyncRestTemplate();
    }

}

更新主要：

public class ApplicationMain {

    public static void main(String[] args) {

        ApplicationContext ctx = SpringApplication.run(SpringConfiguration.class, args);


    }
}

更新的POM：

感谢任何帮助。

Answer 1

在@SpringBootApplication

中添加班级ApplicationMain.java注释

在pom.xml中添加以下插件。构建maven项目并执行jar命令

            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                </configuration>
            </plugin>

Answer 2

在spring-boot项目中，您需要父pom为

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.7.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

您可以删除spring依赖项，例如context，core和beans。

添加到pom

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

再次制作罐子。
